Secure Link Aggregation

2. The method of claim 1, wherein the layer 2 neighbor discovery protocol comprises Link Layer Discovery Protocol (LLDP).

3. The method of claim 1, wherein the device information includes a hostname of the peer network device, an address of the peer network device, or a capability of the peer network device.

5. The method of claim 1, wherein said authenticating comprises determining whether the peer network device is known to the network device as a result of having a previously validated peering session with the network device via the second link.

6. The method of claim 5, wherein information indicative of the previously validated peering session is maintained within a database of the network device.

7. The method of claim 1, wherein said authenticating comprises subjecting the peer network device to a challenge-response authentication mechanism.

8. The method of claim 1, further comprising selectively encrypting, by the processing resource, packets transmitted on the single aggregated logical link.

9. The method of claim 8, wherein said selectively encrypting, by the processing resource, packets transmitted on the single aggregated logical link comprises encrypting control traffic and not encrypting user traffic.

11. The network device of claim 10, wherein the layer 2 neighbor discovery protocol comprises Link Layer Discovery Protocol (LLDP).

12. The network device of claim 10, wherein the device information includes a hostname of the peer network device, an address of the peer network device, or a capability of the peer network device.

14. The network device of claim 10, wherein the peer network device is authenticated by determining whether the peer network device is known to the network device as a result of having a previously validated peering session with the network device via the second link.

15. The network device of claim 14, wherein information indicative of the previously validated peering session is maintained within a database of the network device.

16. The network device of claim 10, wherein the peer network device is authenticated by subjecting the peer network device to a challenge-response authentication mechanism.

17. The network device of claim 10, wherein the instructions further cause the processing resource to selectively encrypt packets transmitted on the single aggregated logical link.

18. The network device of claim 17, wherein selective encryption of the packets involves encrypting control traffic and not encrypting user traffic.
